Specification of Letters Patent.

Patented May 5, 1914.

To all whom it may concern:

Be it known that I, J OHANN F. M. PA- :rrrz, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented a certain new and useful Improvement in Regulators, of which the following is a specification.

This invention relates to improvements in the construction of regulators and particularly in that class known as spring regulators.

The object of the invention is to produce a regulator which is very sensitive in its operation thereby giving closer regulation than has heretofore been attained. To attain this result in regulators it is necessary to have the parts balanced, this being one of the features of the present invention.

A clear conception of the invention can be obtained by reference to the accompanying drawings in which like reference characters designate the same parts.

Figure 1 is a front view, partly in section, of a regulator built according to the invention. Fig. 2 is an'end view of the device shown in Fig. 1.

The casings 1, which serve as the weights and also partially inclose the spring 2, are concentrically supported upon the levers 6, 7, by means of the pins 9. These pins 9 have their axes in the horizontal plane of the axis of the spring 2. The ends of the spring 2 have the supports 3 fixed thereto, these supports 3 being minutely adjustable to various positions along the spring 2 to vary the stiffness of the spring. The adjusting bolts 4, which pass through the ends of the casings 1 and are fixed thereto by the lock nuts 5, are screwed into the supports 3. This means provides for the adjustment of the supports 3 as to their dis tance from casing 1 and hence gives a second adjustment for the ends of the spring 2, within the casings 1, by turning the bolts 4L thus varying the initial spring stress.

Theweights of casings 1 are mounted di rectly and indirectly independently of each other as to mutual guiding, that is, there is no sliding or guiding of the weights, the one upon the other as in the telescoping casings of the prior art, and this independent mounting also avoids any mutual sliding of parts connected to or extended from the weights or casings. The weights or casings 1 are not guided by any means other than the levers 6, 7, thus reducing the friction to a minimum.

The corresponding levers 6, 7, are parallel to each other and are connected to the pins 8 which are pivotally mounted in the bracket 10. The bracket 10 is fixed to the regulator drive shaft 14:, which shaft 14 is connected in any suitable manner, not shown, to the main shaft of the engine. This drive shaft 14 has fixed thereto the spline 15 which allows the horizontal movement of the sleeve 16 along the shaft 14L, at the same time transmitting rotary motion from the shaft 1a to the sleeve 16.

The lever 11 has one end fastened to the shaft 8 to which the lever 7 is connected. The other end of this lever 11 is provided with the pin 12 which forms a pivotal con nection between the lever 11 and the link 13. The lower end of the link 13 is pivoted to the sleeve 16 by the pin 17.

The collar 18 is mounted upon the sleeve 16, this collar 18 being rotatable upon the sleeve 16, but being prevented from lateral shifting thereon by the nut 21. The collar 18 has two guide pins 22 which allow its axial movement relative to the guide 23. This guide 23 is fixed to the upper part of the supporting stand 24 of the regulator.

The link 20 which is pivoted to the collar 18 at its upper end by the pin 19, is connected at its lower end to the lever 27 by a pin 26. The lever 27, having the hub 28, is supported upon the shaft 30, which shaft 30 is supported in the bracket 25. The lever 29 is also attached to the hub 28, so that any movement of the lever 27 will be transmitted to the lever 29 through the hub 28. The valve gear to be regulated is suitably connected to this lever 29, this connection being well known in the art.

In the operation of the regulator the rotary motion of the engine is transmitted to the regulator drive shaft 14. This causes the rotation of the sleeve 16 and, through the levers 6, 7, the upper portion of the regulator. The centrifugal force exerted upon the casings 1 will cause a tension within the spring 2. The forces exerted by the casings 1 will be balanced since only one spring 2 is used. The casings l will'move outward parallel to the spring 2, due to the arrangement of the levers 6, 7. This outward movement of the weights or casings 1 parallel to the spring 2 constitutes motion of translation of the weights not considering rotation, and the weights during such movement have their centers of gravity constantly lying in the axis of the spring.

Any motion of the casings 1 will be transmitted through the levers T, 11, and the link 13 to the sleeve 16. This sleeve 16 will move the collar 18 which will in turn move the links 20 which will act upon the levers 27, 29, and hence upon the valve gear to be operated.

If it is desired to change the speed, the spring 2 may be adjusted by means of the bolts. The sensitiveness is changed by turning the supports 8, thus lengthening or shortening the spring 2 by making effective a greater or fewer number of coils. It can be seen that with this arrangement the action of the forces directly in line with the axis of the spring 2, and the double adjustment of said spring 2, makes the governor more universally applicable. The use of one spring maintains a balancing of the forces exerted by the casings 1.

It should be understood that it is not desired to be limited to the exact details of construction shown and described, for Ohvious modifications will occur to a person skilled in the art.

It is claimed and desired to secure by Letters Patent:
